- Intervention effect The laboratory bioassays with leaf and stem bark (10-200 mg) demonstrated a strong allelopathic effect, reducing lettuce radicle elongation to 7-46.0% and 9-79% of the control, respectively.
- Intervention effect The laboratory bioassays with leaf and stem bark (10-200 mg) demonstrated a strong allelopathic effect, reducing lettuce radicle elongation to 7-46.0% and 9-79% of the control, respectively.
- Intervention effect Aqueous leaf extract (50 mg/mL) completely inhibited (0%) lettuce seed germination and reduced pepper germination to 42%.
- Intervention effect Aqueous leaf extract (50 mg/mL) completely inhibited (0%) lettuce seed germination and reduced pepper germination to 42%.
- Intervention effect However, the root exudate of cashew seedlings did not have any inhibitory effect on the test plants.
- Observation Greenhouse experiments simulating field litter fall revealed significant autotoxicity in cashew.
- Intervention effect Cashew seedlings grown in growth media amended with 10% cashew leaf powder exhibited severe growth suppression after 13 weeks, including a reduction in plant height by 58.2% compared to controls.
- Intervention effect Chlorophyll content, stem girth, and leaf number were also significantly reduced.
